DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to architectural or civil engineering components, steel furniture, steel sheds, vending machines and road products, and more particularly to various metallic components and materials used for architectural or civil engineering applications. It is suitable for use in its applied products.

[0002]

2. Description of the Related Art Generally, when constructing various structures, metal members are often used. Various components made of metal (hereinafter, components for construction and civil engineering are simply referred to as “building components”) are also used for structures for construction and civil engineering. Examples of building members include various metal base materials (referred to as members to be joined) and joining materials (for example, joints such as rivets and flanges, angle steel, channel steel rolled into a special sectional shape, I Various types of steel such as steel, T, H, and Z steels). In addition, the above-mentioned various shaped steels may be used as a core material in a base material, for example.

[0003] Various metal members, including the various building members mentioned above as examples, are used for various applications in various parts of the structure, but the structure to be built has sufficient strength as a whole. For this reason, it has been required that individual metal members themselves have sufficient strength. Conventionally, as a contrivance for this purpose, strength has been mainly provided by increasing the thickness of the base material and the joining material. In addition, for example, a grid-like rib may be attached for the purpose of reinforcing a steel floor plate or a flange.

[0004]

However, when the base material or the joining material is made thicker to have strength, the weight of the metal member itself increases correspondingly, and the cost increases because more material is used. There was a problem of doing it. Further, when the reinforcing ribs are used, the number of steps for constructing a product is increased, and a large amount of labor is required for the construction work, which leads to an increase in manufacturing cost. Further, there is a problem that the product shape becomes complicated.

It is conceivable to use a material originally having a high rigidity as a material of the metal member, but such a material is generally expensive and impractical in that the cost is increased. The present invention has been made in order to solve the above problems, and without increasing the thickness of the metal member itself or using an expensive material, the metal member has sufficient strength. The purpose is to be able to have.

[0006]

According to the structural member for construction or civil engineering of the present invention, a plurality of dimples are formed on at least a part of a metal member. Are relatively convex or concave. For example, a plurality of substantially pyramid-shaped dimples are formed on at least a part of the metal member so as to be adjacent to each other. Intersect with each other, wherein the boundary ridge line and the intersection are relatively concave or convex compared to the dimple-forming surface, and the dimple-forming surface has a convex or concave portion between the opposed intersections. It is concave.

[0007] Here, the arrangement of the dimple-forming surfaces adjacent in one direction to the other direction on the metal member may be an arrangement having a phase difference from each other. Further, a fold is formed on the dimple forming surface between the opposed intersections, and the fold is relatively convex or concave as compared with the boundary ridgeline and the intersection, and the fold is The central portion may be curved so as to be relatively convex or concave as compared with the peripheral portion. The dimple may be formed only on one of the front surface and the back surface of the metal member. Further, at least one of the direction, the size, and the shape of the plurality of dimples may be different depending on a portion on the metal member.

Further, the present invention has a dimple forming surface, a boundary ridge line where the dimple forming surfaces are in contact with each other, and an intersection portion where the boundary ridge lines cross each other, wherein the boundary ridge line and the crossing portion are the dimple forming surface. Formed by a metal member having a plurality of dimples in at least a part thereof, which are relatively concave or convex, and a portion between the opposed intersections of the dimple forming surface is convex or concave. It can also be applied to applied products, examples of which include steel furniture, steel storerooms, vending machines, road supplies and the like.

(See FIGS. 3B and 3C). Further, the fold line 14 is formed so as to be curved such that its central portion is relatively convex as compared with its peripheral portion (see FIG. 3D).

As a result, the dimple forming surface 11 is formed in a substantially pyramid shape in which the center of the fold 14 projects most from the boundary ridgeline 12 and the intersection 13 as the bottom. Here, the fold line 14 is provided only on one diagonal line of the rhombus, but may be provided on another diagonal line. By doing so, the dimple configuration surface 11 becomes closer to a pyramid shape.

As shown in FIGS. 3 (a) to 3 (c),
The dimples 2 of the present embodiment are formed in rows in the horizontal direction and the vertical direction, and the arrangement of the dimples 2 adjacent to each other in the horizontal direction in the vertical direction is about 位 in the vertical direction. It is formed so as to form an array having a phase difference. As shown in FIG. 3E, the crossing portion 13 has a flat surface 15 having a predetermined width without being formed as a sharp corner.

The dimple 2 as described above is formed by, for example, press working or roll forming using an outer mold and an inner mold (male and female dies). here,
The outer mold used is a diamond-shaped boundary ridge line 12 of the dimple 2.
The inner mold has an opening corresponding to the shape of the dimple 2 (the valley of the pyramid), and the inner die has a shape corresponding to the raised dimple surface 11 (the peak of the pyramid) of the dimple 2. By engaging these outer mold and inner mold via a building member, the dimple 2
Is formed.

For example, when manufacturing a hanger as shown in FIG. 1, a substantially pyramid-shaped dimple 2 is formed on a coil-shaped or plate-shaped metal by the above-described manufacturing method, and then the shape of the final product is formed. Process into Alternatively, the substantially pyramid-shaped dimples 2 may be formed after the metal is processed into the shape of the final product or in the process of processing by the above-described manufacturing method.

FIG. 4 is an external view showing an embodiment in which the metal member having the dimple 2 described above is applied to steel furniture. Here, as an example of the steel furniture, a rack as shown in FIG. 4A and a locker as shown in FIG. 4B are shown, but the present invention is not limited to this. It can be applied to various steel furniture such as table, desk, or chair.

In FIG. 4A, reference numeral 3 denotes a column, 4 denotes a shelf receiver, and 5 denotes a shelf plate. The dimple 2 shown in FIG.
Are formed on at least a part of the column 3 and the shelf receiver 4 (the dimples are not shown in FIG. 4A). Further, the dimple 2 may be formed on a mounting bracket (not shown) that joins the supporting column 3 and the shelf receiver 4 as the base material. Further, the dimples 2 may be formed on the shelf 5 as well.

In FIG. 4B, reference numeral 6 denotes a frame, 7 denotes a side panel plate, and 8 denotes an opening / closing door, which are hidden behind the frame 6, the side panel plate 7, and the back and top surfaces of the locker. The dimple 2 as shown in FIG. 1 is formed on a back panel plate or an upper panel plate which is not provided.
Dimples are not shown in (b)). Also, if a mounting bracket is used,
The dimple 2 may be formed also on the door 8.

In the case of manufacturing such steel furniture, substantially pyramid-shaped dimples 2 are formed on the individual base materials and joining materials by the above-described manufacturing method, and then the base materials and joining materials are formed. Is assembled and processed into the shape of the final product. Alternatively, the dimple 2 having a substantially pyramid shape may be formed by the above-described manufacturing method after processing into the shape of the final product or during the processing.

As described above, in this embodiment, by forming a large number of substantially pyramid-shaped dimples 2 on a building member, the building member has extremely excellent strength against external pressure from up, down, left, right, front and rear. Can be made. That is, it is possible to provide a strong strength against an external pressure applied along a direction different from the boundary ridge line 12 of each dimple 2. Further, by forming the boundary ridge line 12 along a direction different from the edge direction (horizontal direction and vertical direction) of the building member (for example, obliquely with respect to the edge direction as shown in FIG. 1), the boundary ridge line 12 is formed. Sufficient strength against external pressure along the direction of.

As a result, the thickness of the base material and the joining material can be reduced by the increased strength, and the weight of the base material and the joining material can be reduced by the reduced thickness. The required cost can be reduced. Further, when the dimple 2 is formed on a building member used as a base material, the base material itself has a sufficient strength, so that it is not necessary to use a conventionally used reinforcing rib or the like. Therefore, the product shape can be simplified, the number of product manufacturing steps can be reduced, and the cost for product manufacturing can be significantly reduced.

In addition, since the weight of each building member can be reduced, the quantity that can be mounted on a transporting vehicle or the like at one time can be increased, and the transportation cost can be greatly reduced. In addition, for on-site workers,
The work is easier due to the lighter weight, and the work efficiency and safety can be improved.

Further, when a structure is constructed using the metal member of the present invention, the sound hits a large number of the dimples 2 and is irregularly reflected and canceled out, so that a sound-muffling effect can be obtained. In particular, in the case of a building, in order to obtain a noise reduction effect, conventionally, a special noise reduction board or the like was attached, but if the metal member of the present invention is used, such a noise reduction board or the like can be used to some extent. You can expect a noise reduction effect.

The width and height of the rhombus of the dimple forming surface 11 constituting the dimple 2 and the depth at the center of the dimple forming surface 11 affect the strength of the metal member. It is necessary to set these to appropriate values in order to have. The dimple 2 may be formed on at least a part of the metal member. However, it is preferable that the dimple 2 be formed on the entire surface because the strength is increased by forming the dimple 2 on the entire surface.

Usually, it is often required that the strength of the metal member is sufficient for an external pressure along the edge direction of the metal member. Therefore, especially when the dimple 2 is formed on a base material having a large area, the dimple forming surface 11 forming the dimple 2
It is preferable not to form the boundary ridge line 12 along the edge direction of the base material.

The dimples 2 may have different strengths depending on the direction, size, shape, or the like of the dimples 2 depending on the portions of the metal member. As the shape other than the rhombus, a polygon such as a pentagon or a hexagon, a circle or an ellipse can be considered. In the case of a circular or elliptical shape, it is not always necessary to provide a phase difference in the arrangement.

Further, in the above embodiment, as shown in FIG. 3D, all the dimple forming surfaces 11 on the member rise in one direction (upward in the drawing) as compared with the boundary ridgeline 12 and the intersection 13. Although the configuration is adopted, the direction of raising may be changed alternately or randomly. With this configuration, it is possible to have a strong resistance to the pressure from both sides of the front and back surfaces of the member.

Further, in the above embodiment, an example was given in which the metal member itself was formed into a dimple shape, but only one of the front and back surfaces of the metal member was formed into a dimple shape, and the other surface was formed into the original material shape (flat surface). ) May be left as is. Alternatively, the other surface may be processed into an arbitrary shape other than the dimple. In this way, the dimple surface is directed to the invisible part of the applied product and the other surface is directed to the visible part, so that the aesthetic appearance of the product is maintained while maintaining sufficient strength. can do.

Further, in the above-described embodiment, an example in which the present invention is applied to building members such as hangers and steel furniture has been described. However, other embodiments can be applied.
For example, as building members, in addition to the above-mentioned hanger, various shaped steels as described in the conventional example, cable racks for carrying electric wires, deck plates used for floor materials of buildings, safety steel plates at construction sites, scaffold plates It can also be applied to siding of houses, ducts, shutters, doors, shutters, steel roofing materials, and the like.

As examples of applied products, in addition to the above-mentioned steel furniture, steel storages, steel packaging, fire extinguishers and switchboards, outdoor equipment for air conditioners, steel equipment such as trash cans, vending machines, soundproof walls and the like. The invention can also be applied to metal road products such as guardrails, bicycle chain covers and mudguards, multimedia devices such as mobile phones and portable personal computers, and OA devices.

In addition, the shapes and structures of the respective parts shown in the above embodiments are merely examples of the embodiment for carrying out the present invention, and these limit the technical scope of the present invention. It is not interpreted. That is, the present invention can be embodied in various forms without departing from the spirit or main features thereof.

[0036]

According to the present invention, as described above, since a plurality of dimples are formed on at least a part of the member, the building member can have extremely excellent strength against external pressure. That is, to increase the thickness of the building member itself,
The building member can have sufficient strength without using expensive materials. Therefore, the thickness of the building member can be reduced by the increased strength, the weight of the building member can be reduced, and the necessary cost can be reduced. In addition, it is not necessary to use ribs or the like for reinforcement, which has been conventionally used, so that the product shape can be simplified, the number of product manufacturing steps can be reduced, and the cost for product manufacturing can be significantly increased. Can be reduced. Furthermore, the sound that hits a large number of dimples is diffusely reflected and canceled out, so that a noise reduction effect can be obtained.
